AIX 安装 RAC 无法发现节点(后遗症。。。）

解决无法发现节点问题后，又留下另一后遗症。。。。。。
安装CRS软件后，在第一个节点运行root.sh脚本时，出现以下错误：

[root@aix213 /]#/u01/crs_1/root.sh

Failed to initialize Oracle Cluster Registry for cluster0

解决方法：
[root@aix213 /]#cat /u01/crs_1/root.sh
#!/bin/sh/u01/crs_1/install/rootinstall/u01/crs_1/install/rootconfig
分析root.sh 执行的脚本：
[root@aix213 /]#cat /u01/crs_1/install/rootconfig

#!/bin/sh## rootconfig.sh for Oracle CRS homes##    This is run once per node during the Oracle CRS install.#    This script does the following:#    1) Stop if any GSDs are running from 9.x oracle homes#    2) Initialize new OCR device or upgrade the existing OCR device#    3) Setup OCR for running CRS stack#    4) Copy the CRS init script to init.d for init process to start#    5) Start the CRS stack#    6) Configure NodeApps if CRS is up and running on all nodes## NOTE: Use sample paramfile in $ORA_CRS_HOME/srvm/admin/paramfile.sample for#       setting CRS parameters# The following commands need to be run before Oracle Cluster Registry is# populated.# This is run during CRS installation and not during RAC
SILENT=falseORA_CRS_HOME=/u01/crs_1CRS_ORACLE_OWNER=oracleCRS_DBA_GROUP=oinstallCRS_VNDR_CLUSTER=trueCRS_OCR_LOCATIONS=/dev/rrac_ocrCRS_CLUSTER_NAME=crsCRS_HOST_NAME_LIST=CRS_NODE_NAME_LIST=CRS_PRIVATE_NAME_LIST=aix213-priv,,aix214-priv,CRS_LANGUAGE_ID='AMERICAN_AMERICA.WE8ISO8859P1'CRS_VOTING_DISKS=/dev/rrac_voteCRS_NODELIST=aix213,aix214

发现
CRS_HOST_NAME_LIST=CRS_NODE_NAME_LIST=
这两个环境变量后面没有赋值，应该是在初期安装CRS时，没有发现节点，通过crs配置文件生成后，而这两个变量无法自动赋值，从而导致执行脚本出错。

1、重新配置 rootconfig.sh
#!/bin/sh## rootconfig.sh for Oracle CRS homes##    This is run once per node during the Oracle CRS install.#    This script does the following:#    1) Stop if any GSDs are running from 9.x oracle homes#    2) Initialize new OCR device or upgrade the existing OCR device#    3) Setup OCR for running CRS stack#    4) Copy the CRS init script to init.d for init process to start#    5) Start the CRS stack#    6) Configure NodeApps if CRS is up and running on all nodes## NOTE: Use sample paramfile in $ORA_CRS_HOME/srvm/admin/paramfile.sample for#       setting CRS parameters# The following commands need to be run before Oracle Cluster Registry is# populated.# This is run during CRS installation and not during RAC
SILENT=falseORA_CRS_HOME=/u01/crs_1CRS_ORACLE_OWNER=oracleCRS_DBA_GROUP=oinstallCRS_VNDR_CLUSTER=trueCRS_OCR_LOCATIONS=/dev/rrac_ocrCRS_CLUSTER_NAME=crsCRS_HOST_NAME_LIST=aix213,1,aix214,2CRS_NODE_NAME_LIST=aix213,1,aix214,2CRS_PRIVATE_NAME_LIST=aix213-priv,,aix214-priv,CRS_LANGUAGE_ID='AMERICAN_AMERICA.WE8ISO8859P1'CRS_VOTING_DISKS=/dev/rrac_voteCRS_NODELIST=aix213,aix214CRS_NODEVIPS='aix213/aix213-vip/255.255.255.0/en0,aix214/aix214-vip/255.255.255.0/en0'
2、删除crs 配置信息
[root@aix213 /]#/u01/crs_1/install/rootdelete.sh
3、修改OCR、VOTE 对应raw 属性
[root@aix213 /]#ls -l /dev |grep ocrbrw-rw----    1 oracle   dba          88,  1 Feb 24 09:51 rac_ocrcrw-r-----    1    oracle   dba    88,  1 Feb 26 08:58 rrac_ocr
[root@aix213 /]#ls -l /dev |grep votebrw-rw----    1 oracle   dba          88,  2 Feb 24 09:51 rac_votecrw-r--r--    1    oracle   dba     88,  2 Feb 26 08:58 rrac_vote

4、清空OCR、VOTE 磁盘头信息(所有节点）
[root@aix213 /] dd  if=/dev/zero  of=/dev/rrac_ocr  bs=1024k  count=2560
[root@aix213 /] dd  if=/dev/zero  of=/dev/rrac_vote  bs=1024k  count=2560
5、重新运行root.sh

[root@aix213 /]#/u01/crs_1/root.sh

至此，问题全部解决！
